Title: Improvements in or relating to apparatus for storing stacked articles on counter-balanced supports
IPC: A47B77/10
Filed: 1939-06-27
Abstract: 530,590. Counter-balancing devices. GIBBS, W. J. June 27,1939, No. 18680. [Class 78 (ii)] A receptacle for storing stacks of trays, plates, saucers and the like is provided with means for maintaining the top member of the stack at a pre-determined height. The stacked articles 40, Fig. 3, rest on a carrier 18 having lugs 16, 17 at its corners to which are connected chains 14, 14<SP>1</SP>, 15, 15<SP>1</SP>. These chains pass over sprockets at the top of the casing 10 and extend downwards to lugs 22, 22<SP>1</SP>, Fig. 4, which connect them. A tape 24 connects the lug 22 to a winding drum 25 fast on a shaft 26 which is connected by gears 31, 32, to a shaft 33. The lug 22<SP>1</SP> is connected to an endless chain 28 which passes around a sprocket 30 on the shaft 26. Drums 34 on the shaft 33 have chains 35 connected to them which are attached to tension springs 36 anchored to a bar 37 near the top of the casing. The springs are of such strength that the addition or removal of an article results in a lowering or raising of the carrier 18 to such an extent that the top article remains at a substantially pre-determined elevation with respect to an opening 41 in the casing. The number of articles in the stack at any time is shown by an indicator 50 which is actuated by the shaft 21 through screw-andnut mechanism 46, 47, a link 48 and a crank arm 49. Cutlery is stored in receptacles 55 and table-napkins in boxes 57. A tray taken from the stack may be placed on a shelf 56 while being supplied with cutlery &c. In a modification the stack support 157, Fig. 16, is attached to an endless chain 154 which passes over a sprocket on a shaft 152. A shaft 167 is driven from the shaft 152 by chain-andsprocket gearing and carries a pinion 168 which drives a gear 170. A pinion 172 fast on the shaft carrying the gear 170 engages a rack 173 which is fixed to the piston rod 175 of a dashpot 176. A compression spring 180 co-operates with the dash-pot. In another modification the counter-balancing is effected by an articulated weight 186, Fig. 17. In a further modification the counter-balancing spring 240, Fig. 23, is held between a fixed member 236 and a movable member 242 connected by a chain 250 which is of such a length that the member 242 is at a pre-determined level with no load. This length is adjusted by movement of a screw 246 in a nut 245 connected to the chain.

Title: Improvements relating to the connecting of circuits in telephone systems
IPC: H04M3/523
Filed: 1927-07-15
Abstract: 296,170. Siemens Bros. & Co., Ltd., and Grinsted, W. H. July 15, 1927. Automatic exchange systems; manual exchange systems.- Means for minimizing the possibility of simultaneous connection of more than one of a set of primary circuits to a common secondary circuit comprise sets of two or more interconnected slow-release or slow-to-energize relays individual to the primary circuits, which during their relatively short time of energization permit and during their relatively long period of release prevent connection, the periods being in general out of phase. The arrangement is described with reference to manual operators' connections to orderwires, and also to preselectors when several primary circuits are awaiting a free outlet. For an inter-exchange call an operator depresses key OW, Fig. 1, energizing relays B, E, and if the order-wire is free test-relay T immediately operates, shorts its high-resistance winding to busy the wire and de-energizes relays B, E. If the wire is engaged, relay T does not operate busy tone BT is connected to the operator's headset HS and relays E, F, G pull up in turn, relay G breaking the testing circuit and the circuit of relay E so that E, F. G release in turn, followed by the re-energization of E, testing being prevented until E pulls up, when the cycle is repeated. Due to variations in manufacture, the periodic times of different sets of relays E, F, G will vary, and if several operators are waiting for an order-wire to become free, their times of testing will be out of phase. The relays T are designed so that two such relays will not energize at once over an order-wire, in case simultaneous testing took place. If a preselector, Fig. 3, has a free outlet, when line relay R operates, the switch searches under control of interrupter I until a free outlet is found when test relay T operates. If all outlets are busy, hunting is prevented by a group control relay GP, which also closes the initiating circuit for the relay-sets E, F, G of the preselectors in the group. There is a relay group individual to each primary circuit, but a set of relay groups may be used for a number of sets of primary circuits.

Title: Shank button feeder
IPC: D05B73/12
Filed: 1960-05-30
Abstract: 919,561. Sewing machines. EMSIG, S., EMSIG, J., and SUCHER, J. R., [trading as EMSIG MANUFACTURING CO.]. May 30, 1960 [June 24, 1959], No. 19020/60. Class 112. [Also in Group XXX] In a shank button sewing-machine the shanks S of buttons pass from a hopper into a gap 14 between front walls 12, 13 of a shoot having a back wall 11 engaging the heads H of the buttons. The lower end of the shoot is attached to a presser foot 18, on the lifting of which a finger 30 on a pivoted pawl 22 is advanced to engage the shank of a button B<2> and shifts the latter from a position in which the shank is releasably held by the curved nose 55 of a spring- biased pivoted pawl 45, to the sewing position in which it is held on an anvil A by spring fingers 16, 17. The button B<2> replaces the button B<1> initially in the sewing position, and a button B<3> slides downwardly till its shank engages the nose 55. The arrangement enables a range of buttons having different sized heads but shanks of uniform size to be fed. The distance between the leading edge 30a of finger 30 in the advanced or sewing position and the nose 55 is made equal at least to the difference between the diameter of the head of the largest button and the width of the shank. The finger 30 is arranged to enter the path of the button shanks at a position such that the distance between the edge 30a and the nose 55 is greater than the width of a shank but less than the diameter of the head of the smallest button. Pawl 22 is pivoted at 23 to one end of an arm 20, the other end of which is pivoted at 21 to the shoot. A spring 36 acts on pawl 22 to bias a stud 25 on arm 20 against the fixed head H<1> of the machine. When the presser foot is raised, arm 20 is thereby swung relatively to the shoot and a cam surface 31 on pawl 22 cooperates with a stud 35 on the shoot to impart the appropriate feeding movement to finger 30, an abutment 31a engaging stud 35 to stop finger 30 in the sewing position. Pawl 45 is pivoted at 46 to the shoot. A spring 48 acts on pawl 45 to bias a tail 52 thereon against an abutment 53 rigid with the shoot, and the nose 55 into the path of the shanks. Specifications 720,320 and 776,001 are referred to.

Title: Process for the preparation of ferrous leuco-ferrocyanide and prussian blue
IPC: C09C1/26
Filed: 1960-05-30
Abstract: Ferrous leuco-ferrocyanide is prepared by heating hydrogen cyanide with ferrous sulphate and a basic substance in aqueous solution in a non-oxidizing atmosphere, for example nitrogen, the amounts of reagents being so chosen that a pH of 3,5 to 5,5 is maintained during the reaction, and thereafter acidifying and boiling.  The reaction may be carried out in the presence of ammonium sulphate.  The base may be an amino compound, magnesium carbonate, alkali metal acetate, or alkaline earth metal hydroxide.  Examples employ ammonia, diethylamine, sodium carbonate, potassium acetate, and ammonium acetate, as the base. Preferably a ferrous sulphate solution is saturated with hydrogen cyanide, which may be in the form of the gas obtained by reacting ammonia and methane on a platinum base catalyst. In examples the made up solution is heated to 50 DEG C. for 30 minutes, acidified to pH 1 and boiled for 3 hours, to obtain a white crystalline precipitate of the leuco-ferrocyanide.  The leuco-ferrocyanide may be oxidized to Prussian blue preferably with an aqueous potassium chlorate solution.  The process may be carried out batchwise or continuously.

Abstract: 953,666. Electric switches. B. C. VON PLATEN. May 29, 1961 [June 11, 1960], No. 19322/61. Heading H2B. An electric switch comprises two leaf springs 37, 32, each fixed at one end, the latter carrying a contact bar 31 at its free end which cooperates with and shorts a fixed pair of frame mounted contacts 30a, 30b, and a magnetic armature 41, the spring 37 carrying a permanent magnet 40 at its free end and being subjected to a force exerted by the expansion and contraction of a thermo-responsive member device 1 such as rubber which moves the spring 37 until the magnet 48 attracts the armature 41 which comes to rest against a stop 42 and leaves a mutual residual air gap when the contact circuit has been completed. A chamber 27 of a refrigeration thermostat lined with an insulating material contains the springs 32, 37 which may comprise a single component, and are fixed to a synthetic resin foundation 36 by a rivet 38. An ambient temperature dependent expansion of the member 1, hermetically sealed in the housing 2, is transmitted to the spring 37 through mica disc 29, by a piston 9 itself housed in a centra] conical shaped lip 5 of a rubber disc 3 permanently held against a ridge 4. The outside surface 8 of the lip 5 is as radially narrow as possible. A small chamber 10 formed by the central portion of the piston 9 collects rubber swarf formed by the piston's movement, thus limiting mutual piston and housing friction. The piston wall surface contact " h " is made less than one-fifth of the piston radius in order to reduce friction and the piston stroke is arranged not to exceed 0.1 mm. Outward piston movement causes the magnet 40 to approach the armature 41 until this is attracted upwards and an electric circuit is completed between fixed contacts 30a, 30b set in the foundation 36, by a silver strip 31 loosely mounted on the spring 32. Contact leads 33a, 33b pass through an epoxy resin plug 34 moulded in a thin walled cap 35. A screw 43 limits the possible travel of piston 9. Conic leaf springs 11 are joined by a bolt 15, nut 16 and discs 17, 18. The thermostat may be set by means of a shaft 21 screwed into a disc 20, thus exerting pressure on the rubber 1 through the bolt 15 and a sealing membrane 19. Rubber 1 may be silicone grease lubricated and by its insertion into the casing 2, will increase the air pressure in the contact chamber 36. The above switching sequence may be adapted to open the contacts 30a, 30b with an expansion of the rubber 1, if the device is to be used as a heater thermostat.
